MAGAZINE-STOVE.

SPECIFICATION forming part of Letters Patent No. 286,235, dated October 9, 1883.

Application filed June 4, 1883. No model.)

f0 aZZ whom it may concern Be it known that I, SAMUEL SMYTH. of fPittst-on, in the county of Luzerne and State of Pennsylvania, have invented an Improve ment in Magazine-Stoves, of which the following is a specification.

Magazine-stoves have been provided with swinging or with sliding cut-off devices; but when the cut-off is moved aside for allowing the coal to descend to the fire considerable space at one or both sides of the magazine is required for such cut-oif to pass into.

My improvement is made for rendering the cut-off device compact and capable of being turned so as to support the fuel, or partially :revolved to separate and deliver upon the fire-bed a given quantity of fuel, or else turned aside to allow the fuel to descend gradually into the fire, and when turned aside it occupies little or no more space than the lower end of the magazine.

In the drawings, Figure 1 is a vertical section of the magazine with the improved cutoff applied thereto, and Fig. 2 represents a modification in the shape of the cut-off.

The exterior of the stove and the grate and fire-pot may be of any desired character, and as such magazinestoves are well known the same do not require to be illustrated or furto the pivots or arbors c c, that pass through the end plates, 1', of the hopper, and are provided with segmental gears represented by dotted lines, so that the cut-offs can be partially rotated by a crank-handle applied to one of the pivots. It will now be seen that when turned into the position shown by full lines, Fig. 1, the fuel in the hopper will be supported by the cut-off plates (1 d; but when partially turned, so as to occupy the position progresses.

shown by dotted lines, such cut-off plates will be within the cheek-pieces I), and entirely out of the way, so that the fuel can descend gradually to the fire as the combustion Usually the cut-off plates will receive a half-rotation, and in. passing from the lowest position to the highest a section of fuel will be separated from the mass of fuel in the hopper and discharged into the fire. This is to be done periodically, and a regular amount will be supplied, even though the attendant may'not be able to observe the con dition of the fire. If the cut-off plates are made flat, or nearly so, and extend across the axes or arbors, as shown in Fig. 2, they may be turned flatwise or horizontal. to support the fuel, or turned up edgewise to allow the fuel to pass through between the cut-off plates; or the said cut-oif plates may be made in a similar sectional shape to the grate-bars shown in my Patent No. 143,856, and illus trated by the dotted lines in Fig. 2. In this case a section of fuel will be separated from the magazine and delivered on the fire, as be fore described, and then the cut-offs are to be turned back to allow the fuel to drop upon the segments in their lowest position, ready for the next feed to be effected by turning the cut-offs, as before stated. There are preferably ledges Z at the lower parts of the hopper above the cheeks I), so that the fuel will not interfere with the turning of the cut-off plates first one way and then the other below such ledges. If the ledges Z are dispensed with, the sides of the hopper will usually be inclined, as indicated by the dotted lines at a, Fig. 2.

I am aware that a revolving valve located in the lower part of the magazine, for opening or closing the passage-way for the coal by a partial rotation of such valve, has been used; hence the same is not claimed herein.

I claim as my invention- 1. The combination, with the magazine in a stove, of two cut-off plates, axes for the same, and gears to connect the axes, substantially as specified.

2. Two segmental cut-off plates, geared together and provided with a handle or wrench to partially rotate such cut-offs, whereby the of the magazine having a ledge above the 10 fuel is either supported by the cut-offs or the cut-offs, and the cheeks extending below the required amount fed down to the fire-bed, bottom of the ledges, substantiallyasspecified. substantiallyas set forth. Signed by me this 29th day of May, A. D. 3. The combination, with the magazine, of 1883. downwardly-projecting cheek-pieces, cutoff V SAMUEL SMYTH. plates, axes, and gearing, substantially as Witnesses: specified. Gno. T. PINCKNEY, 4.
